  • Publication number: 20160286587
    Abstract: A wireless device, such as a mobile device, for example, pairs with a peripheral device, such as a wristlet, for example, worn by the user. One or both of the wireless device and the peripheral device, each of which contact the user's skin, determine whether the other is in contact with the body of the same user. If both devices are in contact with the same body, the devices will pair with each other.

  • Publication number: 20160262116
    Abstract: A system including a wireless communication device and a peripheral device communicate with each other using radio frequency (RF) waves that are propagated using a user's own body as a transmission medium. The wireless communication device selectively controls the transmit output power of the peripheral device to cause the peripheral device to transmit data and information in a low-power transmission mode. This minimizes the amount of RF waves that are received at the wireless communication device as reflected RF waves, but helps to ensure that the RF waves that do reach the wireless communication device are transmitted as surface waves along the user's skin. Responsive to the receipt of the surface waves, and based on a validity of the information carried by those surface waves, the wireless communication device transitions from a locked state to an unlocked state.

  • Publication number: 20160259926
    Abstract: According to one aspect of the present disclosure, a method is implemented by a mobile computing device to authenticate a user. A first signal indicative of a body tremor of a limb holding the mobile computing device is detected. A second signal indicative of a body tremor of a limb to which a separate wearable computing device is secured is also detected. Based on a comparison of the body tremors, a determination is made as to whether the limbs are the same limb. A user account associated with the wearable computing device is authenticated based on the determining indicating that the limbs are the same limb.

  • Publication number: 20160249211
    Abstract: A user of a cellular telephone also has a peripheral device, such as a wristlet or ring, for example, that is worn on, and contacts, the user's body. When the user depresses a user control, such as a power button or other control on the cellular telephone, a Body Area Network (BAN) communication link is established between the cellular telephone and the peripheral device. The BAN link utilizes the user's body as a transmission medium to carry data between the cellular telephone and the peripheral device. Additionally, a passcode stored at the peripheral device is sent to the cellular telephone over the BAN link. If the passcode is valid, the device will bypass a passcode entry screen and unlock the cellular telephone for the user.

  • Publication number: 20080293448
    Abstract: According to the invention a first communication device investigates if there is an entry of a contacting identifier received in the device in a contacts register. In case there is no such entry it locates, in the contacts register, communication devices in a set of communication devices providing a lookup service, which set includes at least one communication device and where at least one communication device is a personal communication device, an sends a query regarding the contacting identifier to at least one second communication device of the set. The second communication device receives the query and investigates an own contacts register. In case the contacting identifier is provided in the own contacts register it further locates an identity associated with the contacting identifier and automatically sends data regarding the identity to the first communication device as a response to the query.
